We performed surgical treatment for cerebellar metastasis of relatively rare small-cell neuroendocrine carcinoma (SCNC) of the urinary bladder. On preoperative imaging, the lesion was solitary, and the edema around the tumor was unremarkable; thus, other differential diagnoses besides a metastatic brain tumor were also considered preoperatively. Intraoperatively, the tumor was soft, and the circumference brain and boundary were indistinct and easily hemorrhagic. The tumor was grossly totally removed, and postoperative radiotherapy was added. The clinical symptoms of the patient were relieved, and he was discharged on foot. Thus far, relatively few reports have described surgical treatment of brain metastases of SCNC of the urinary bladder. We herein report a case of metastatic brain tumor due to SCNC of the urinary bladder that required surgical treatment, along with a review of the previous literature regarding its clinical features and the characteristics of intracranial lesions related to surgery, such as imaging and intraoperative findings.

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease featuring progressively expanding intracranial hematoma. We treated a man in his 70s with bilateral cerebellar CEIH. He had presented at another hospital with dizziness, and imaging showed two independent hemorrhagic space-occupying lesions in the bilateral cerebellar hemispheres. The symptoms progressed relatively rapidly, and there were signs of impending cerebellar herniation; he was transferred to our institution, and emergency surgery was performed. The operative findings included a hematoma with partial capsulation. We diagnosed CEIH from preoperative magnetic resonance imaging and computed tomography findings, clinical course, and pathological findings. The postoperative course was satisfactory. We present this case of bilateral cerebellar CEIH, as an extensive search of the literature suggests that this has not been reported before. Although CEIH is a condition that is usually hard to diagnose preoperatively, good outcomes can be achieved with appropriate surgical treatment. It is therefore important to keep this clinical entity in mind and not miss the right timing to operate.
